Can. 1283 Before administrators begin their function:
1° they must take an oath before the ordinary or his delegate that they will administer well and faithfully;
2° they are to prepare and sign an accurate and clear inventory of immovable property, movable objects, whether precious or of some cultural value, or other goods, with their description and appraisal; any inventory already done is to be reviewed;
3° one copy of this inventory is to be preserved in the archive of the administration and another in the archive of the curia; any change which the patrimony happens to undergo is to be noted in each copy.
